TS-930 Mode Switch Repair

My friend Oliver WB3KLI had a Kenwood TS-930 in which the mode switch had failed.  Although it appears the mode switch is a rotary knob switch, it really turns a linkage that in turn pushes and pulls a slide switch.  Since the slide switch and the linkage failed and is no longer available I converted it to use a standard wafer, rotary switch.  I found several on eBay, but none had enough contact points.  I needed a 6P6T switch.  I ended up building my own switch from a combination of wafers from 2 separate switches.  You can see the photo album of my rebuild project here.  Or click on the picture below.
